Nanotechonology application in food includes nanofood when nanoparticles, nanotechnology techniques or tools are used during cultivation, production, processing, or packaging of the food. It does not mean atomically modified food or food produced by nanomachines. Future applications of nanotechnologies could include nanostructured food products, nanoscale or nano-encapsulated food additives, or food packaging with improved properties. There are, however, certain foods including food additives that naturally contain nanoscale particles.
